我定义了一个新的存储过程,但在调用它时出错,
CREATE OR REPLACE PROCEDURE SCOTT.getempsal(
p_emp_id IN NUMBER,
p_emp_month IN CHAR,
p_emp_sal OUT INTEGER)
AS
BEGIN
SELECT EMP_SAL
INTO p_emp_sal
FROM EMPLOYEE_SAL
WHERE EMP_ID = p_emp_id
AND EMP_MONTH = p_emp_month;
END getempsal;
并试图称之为:
getempsal(1,'JAN',OUT) --Invalid sql statement.
